Abstract
Determining cache value currency using persistent markers is disclosed herein. In one example, a cache entry is retrieved from a local cache memory device. The cache entry includes a key, a value to be used by the computing device, and a marker flag to determine whether the cache entry is current. The local cache memory device also includes a marker location that indicates a location of a marker in a shared persistent fabric-attached memory (FAM). Using a marker location, the marker is retrieved from the shared persistent FAM. From the marker and the marker flag, it is determined whether the cache entry is current. The shared FAM pool is connected to the local cache memory devices of multiple computing devices.
